如何：从另一个应用程序中加密文件 [英] How to: Encrypt a file from within another application

问题描述

大家好：

有没有人知道如何使用第三方加密工具对主应用程序中的文件或项目进行编码？



例如：

我启动MS-Word来创建一个新文档，但是当我保存它时，当我从MS-Word应用程序保存文档时，文档会被加密。 />


谢谢，

Hi everyone:
Does anyone know of a way to use a third party encryption tool to encode a file or project from within the main application?

For example:
I start MS-Word to create a new document, but when I save it, the document is encrypted when I save it from the MS-Word application.

Thanks,

推荐答案

我在C-NET上看到了一个应用程序叫捕食者。 Predator将一个密钥写入USB驱动器，当USB驱动器插入您的计算机时，访问被授予，当您被移除时，您的PC被锁定。



加密应用程序I我想到的是：当插入USB驱动器时，你创建的任何东西都会被加密，但是如果没有USB驱动器则会正常保存。

I saw on C-NET a application called Predator. Predator writes a key onto a USB drive and when the USB drive is inserted into your computer access is granted, when removed your PC is locked down.

The encryption application I had in mind is: When the USB drive is inserted anything you create will be encrypted, but if the USB drive is absent it is saved normally.

正如TRK3所说，加密过程取决于您选择的加密工具/库。但是，使用外部库的一个大问题是，在使用最初创建它的应用程序（例如MS Word）访问文件之前，您必须经历解密过程。如果MS和其他应用程序制造商允许你动态地构建插件来加密/解密（这不是我所知道的，但我想他们正试图避免负债），这将是很好的。让其他人做插件）。



我查了一下Predator USB驱动器，它只是一个锁定设备，没有加密。当然，这种锁定装置很容易被绕开，所以它实际上并不比普通系统密码更安全。



忘了提，很多驱动器现在也支持批量加密，因此您可以阅读。取决于您的目标是什么（保持某些数据安全而不是让整个系统保持安全而不让您的朋友查看您的文件），这也可能有助于了解。

As TRK3 said, the encryption process will depend on the encryption tool/library that you choose. Big problem with using external libraries though is that you''ll have to go through the decryption process before you can access the file with the application that originally made it (for example MS Word). It would be nice if MS and other application makers would allow you to build plug-ins to encrypt/decrypt on the fly (that doesn''t exist that I know of, but I guess they''re trying to steer free of liabilities of having other people make plug-ins).

I looked up that Predator USB drive and it''s simply a locking device, there''s NO encryption. Of course, this locking device can easily be circumvented so it''s really no safer than a regular system password.

Forgot to mention, a lot of drives also support bulk encryption now as well, so you can read up on that. Depending on what your goal is (keep certain data secure vs. keep a whole system secure vs. keep your friend from looking at your files), that may also be helpful to know about.

致TKR3和Albert Holguin：

感谢您的建议。我之所以将其标记为C ++，Linux是因为我想用C ++编写Cypher工具的原因，我不能仅仅将其标记为C ++问题。



我担心我无法按照我的想象创建应用程序。看起来我必须找到另一种方法。



再次感谢，

To TKR3 and Albert Holguin:
Thanks for your advice. The reason I tagged it C++, Linux was I wanted to code the Cypher tool in C++ for standalone reasons, and I couldn''t just tag it as a C++ problem.

I was afraid I couldn''t create the application as I envisioned it. Looks like I''ll have to find another approach.

Thanks again,
